Get categories for multiple transactions
Fetch category assignments for many transactions in a single request. Use this instead of calling GET /api/transaction-categories/ once per transaction; it collapses what would be N requests into one. Accepts up to 500 transaction IDs per call. Unknown or not-yet-categorized IDs are returned with an empty array.
Authorizations
First-party access token for your own signed-in session, obtained from the /api/enterprise-auth/login endpoint. The REST API returns your own account data to you — it is a first-party consumer surface, not a third-party integration channel. Data from connected bank feeds (open-banking / CDR data) is your own data, returned only to you in your own authenticated session.
Body
Transaction IDs to fetch categories for (maximum 500 per request).
